How it Works

The converter uses the browser’s Intl.DateTimeFormat and toLocaleString APIs with IANA timezone identifiers (e.g., America/New_York). It calculates the UTC offset for the source timezone, converts to UTC milliseconds, then formats the result in the destination timezone. This handles daylight saving transitions correctly.
